You should see a white precipitate form.
The chemical equation is
AgNO₃(aq) + NaCl(aq) → AgCl(s) + NaNO₃
Answer:
Methanol is more acidic than the alkyne and will be deprotonated instead.
Explanation:
of methanol is around 15 and
of terminal alkyne is around 26.
, where
is acid dissociation constant
So, higher the acidity of an acid, higher will its
value and thereby lower will be its
value.
So, methanol is certainly stronger acid than terminal alkyne.
Hence sodium amide preferably deprotonates methanol instead of terminal alkyne.
Hence, option (A) is correct.
Answer: 3.67 x 10^24
Explanation: 1mole of Cr contains 6.02x10^23 atoms
Therefore 6.098moles of Cr will contain = 6.098 x 6.02x10^23 = 3.67 x 10^24
Multiply first the mass given in kilograms by 1000 in order to convert it to grams.
(0.23 kg) (1000 g / 1kg) = 230 g
Then, divide the mass in gram by the molar mass of SO2
molar mass of SO2 = 64.044 g/mol
Solving for the number of moles,
(230 g)(1 mol/64.044g) = 3.59 moles
Thus, there are approximately 3.59 moles of SO2 present in 0.23 kg of SO2.
3 teaspoons equal to 1 tablespoon in the metric conversions.
